To a/ZZ whom, it may concern:

Be it known that I, WILLIAM A. SCHRAUB- sTADTER, a citizen of the United States, and a resident of the city of St. Louis and State of Missouri, have invented certain new and use ful Improvements in Type-Perfecting Mechanism, of which the following is a specification.

My invention relates to type-perfecting, and has for its principal objects to perform the perfecting operations at a distance from the type-casting mold, to perfect the type singly, to accomplish certain results heretofore accomplished only by hand-labor, to provide for securing type with the jet thereon, and to attain certain other advantages hereinafter disclosed.

In the accompanying drawings, which form part of this specification, and wherein like symbols refer to like parts wherever they occur, Figure I is a vertical view of my perfecting mchanism applied to a type-casting machine, which is shown in section. Fig. II is an end elevation thereof, and Fig. III is a side elevation of said perfecting mechanism. Fig. IV is a plan view of the perfecting mechanism, the device for connecting it to the actuating mechanism being broken away. Fig. V is a vertical sectional detail through the type-ej ecting plunger of the forming mechanism and the pusher-bar of the type-gripping carrier of the perfecting mechanism.

Heretofore type-casting machines have been devised which comprised, among other parts, actuating mechanism and a reciprocating mold-cover, the mold-cover being provided with a jaw in which the type remains while undergoing some of the operations of the machine thereon. On account of the necessarily short stroke of the mold-cover some of the perfecting devices in such vmachines were located on or so close to the mold that there was great danger of chips flying into the mold.

For this purpose an arm 3 is mounted to oscillate in a vertical plane and in such a position that when said arm is upright its upper end is directly below and in register with the jaw 1 of the mold-cover 2 of the type-casting mechanism. Mounted in a longitudinal socket in said oscillating arm so as to slide endwise thereof is a pusher-bar 6. This pusher-bar has a pin 7 projecting through a slot in said arm and is provided with a spring 8, which is under compression and bears at one end against said pin and at its other end against a lug 9, provided therefor on the outer end of said arm, whereby said spring tends to force said pusher-bar back toward the pivotal end' of said oscillating arm. The outer end of the pusher-bar has lateral eXtensions, and the end of the oscillating arm is grooved to permit the extending end of the pusher-bar to enter therein. This groove is arranged to be in direct register with the clamping-j aw of the mold-cover when the oscillating arm is in its vertical position. In order to determine the proper vertical position of said arm, a screw 10 is located on the frame of the casting-machine in position for the oscillating arm to bear against. Said screw thus constitutes an adjustable stop for limiting the vertical position of said arm.

The arm 3 is mounted upon a shaft 10a, which is provided with a crank-arm 1 1,which in turn is connected by a pivotal link l2 tol a lever 13,having a fulcrum 13'GL in the main frame and arranged to be actuated by a cani 14 on a shaft 15 of the actuating mechanism. The connecting devices are so arranged as to produce a rocking or oscillating motion of the arm 3 through an arc of about ninety degrees, more or less. Also suitably connected to the actuating mechanism so as to be driven thereby is a rock-lever 16, whose end is in position to bear against the projecting pin 7 of the pusher-bar 6 when the oscillating arm 3 isv in its lowermost or horizontal position. For this purpose the rock-lever 16 is fulcrumed on a shaft 16, mounted on the frame of the perfecting mechanism so as to swing in a vertical plane, and its end is connected by a pivotal link 17 to a lever 17a, having a fulcruni 17b in the main frame in position to be operated by a cam 18 on a shaft 15 of the actuating mechanism. The power-transmitting devices are so arranged that the rock-lever I6 will actuate the pusher-bar 6 on the arm 3 as soon as said pusher-bar reaches its horizontal position.

The outer end of the oscillating arm 3 is beveled on its under side'. Fixed to the frame- IOO ITO

work in position to limit the downward movement of said oscillating arm is a back-stop 19, beveled to correspond with the beveled outer end of said oscillating arm. This back-sto 19 constitutes one wall of a vertical channe threaded hole through which works an adjusting-screw 23, arranged to bear against the framework and force said flange away therefrom. By this means the vertical channel may be adjusted to any desired width.

The vertical channel has perfecting-knives 24, arranged on each side thereof, said knives comprising sharp-edged plates slotted lengthwise and set at an angle to the walls of the channel. Said plates 24 are clamped by means of screws 25, so that all that is necessary for adjusting them is to loosen the screws and shift said plates endwise and again clamp them in any desired position. y

Mounted above the vertical channelso as to slide therein is a T-bar or plunger 26, whose end portion fits in said channel and constitutes a plunger for forcing a type therein to the lower end of said channel. This lastmentioned plunger 26 is actuated by the driving mechanism, from which motion is transmitted to it by any suitable transmitting devices. As shown in the drawings, said plunger 26 has a pin 27 projecting through a slot 28 in the portion 45 of the framework, which constitutes a guide therefor and is connected by a .pivotal link 29 to a lever 30, having a fulcrum 30"L on the main frame in position to coperate with a cam 31, provided therefor on a shaft 15 of the driving mechanism. The parts are so arranged that the downward movement of the plunger 26 occurs just after the type has been forced into the top of the channel by the operation of the vpusher-bar 6. At the lowermost portion of said vertical channel is a horizontal channel 32, adapted to receive the type directly from 'said vertical channel. The walls of this horizontal channel are provided with perfectingknives 33, similar to those provided for the vertical channel, and the walls of said horizontal portion and the perfecting-'knives thereon may be .made adjustable, as in the case of the walls and knives of the vertical channel. Opposite the lower end of said vertical channel is a horizontal pusher 34, mount- For this purpose the wall of the ved in guides provided therefor in the framework to slide in alinement with the horizontal portion of said channel. This pusher 34 has pins 35 projecting laterally therethrough, which rest between the forks of a yoke 86. The stem 37 of this yoke works in a socket provided therefor in the end of one arm of a bell-crank lever 38. In this socket is a spring 39, arranged to press said yoke outwardly to keep it in engagement with said pins. The other end of said bell-cranklever is connected by a pivotal link 4() to a lever 41, fulcrumed on the main frame and arranged to bear against a cam 42 on a shaft 15 of the actuating mechanism. The parts are so arranged that the horizontal pusher-bar 34 is moved forward just. after the vertically-moving pusher-bar has reached the lower limit of its stroke, so that the type at the bottom of the vertical portion of the channel is forced into the horizontal portion thereof and the entire y row of type in said horizontal portion is moved bodily to pass the perfecting-knives 33. The several parts which coperate with the several cams are preferably held in engagement therewith by means of springs 43, suitably arranged for the purpose.

The machine is provided with a knife or sharp-edged bar 44, arranged to project into position for a type in the jaw of the mold-cover to be carried against it by the movement of said mold-cover. This knife 44 thus removes the jet formed on the end of the type by the operation of casting. breaker has been mounted iXedly with reference to the mold of the casting-machine but as it is desirable occasionally to obtain type with the jet thereon the et-breaker is preferably mounted on a part which is movable or separable from the casting mechanism. As shown in the drawings, the et-breaker is mounted upon the frame 47 of the perfecting mechanism.

The frame 47 of the perfecting mechanism is mounted `to slide in guides provided therefor in the bracket 48 or other portion of the main frame of the machine provided for its v support. The guides, as illustrated in Figs. I and II of the drawings, may consist of a horizontal rib 49 in the side of the supporting-bracket 48, the rib being arranged to fit a groove provided for the purpose on the frame 47 of the perfecting mechanism. The perfecting mechanism is slidingly held in position upon the supporting-bracket by means of a hook 50, which is secured thereto and overhangs the top of said supporting-bracket. An elongated horizontal slot 51 is formed in the frame of the perfecting mechanism, and through this slot extends a threaded bolt 52, which secures the perfecting mechanism firmly to the supporting-bracket. The devices for transmitting power from the actuating mechanism to the perfecting mechanism have separable connections. For in- Heretofore the jet-,

stance, the pin or screw-bolt 46, which secures the lever 16 to the link 17, is made removable or detachable. So, too, the pins or screw-bolts 46, Which secure the respective links 12, 29, and 40 to their respective actuatilng-levers 13, 30, and 41, are made removab e.
